THIS
EXECUTIVE CHANGE IN CONTROL AGREEMENT (Agreement) is made as of August 11,
2004, by and between Infodata Systems Inc., a Virginia corporation (the
Company), and _________________ (the Executive).

WHEREAS,
the Board of Directors of the Company has determined that appropriate steps should be
taken to reinforce and encourage the continued employment and dedication of the
Companys key personnel.

NOW,
THEREFORE, as an inducement for and in consideration of the Executive remaining in its
employ, the Company agrees that the Executive shall receive the severance benefits set
forth in this Agreement in the event the Executives employment with the Company is
terminated pursuant to or after a Change In Control (as hereinafter defined) of the
Company under the circumstances described in this Agreement.

1.       Key
Definitions.

As
used herein, the following terms shall have the following respective meanings:

1.1       
     "Cause" means:

(a)                 the
Executives willful and continued failure to substantially perform           his/her
assigned duties as an officer of the Company (other than any such           failure
resulting from incapacity due to physical or mental illness), which           failure is
not cured within thirty (30) days after a written demand for           substantial
performance is received by the Executive from the Board of Directors           of the
Company which specifically identifies the manner in which the Board of
          Directors believes the Executive has not substantially performed the
          Executives duties; or

(b)                 the
Executives willful engagement in illegal conduct or gross misconduct
          which is materially and demonstrably injurious to the Company.

For
purposes of this Section 1.1, no act or failure to act by the Executive shall be
considered willful unless it is done, or omitted to be done, in bad faith and
without reasonable belief that the Executives action or omission was in the best
interests of the Company; provided, however, that the failure by the Executive to cure
within the time period set forth above in Section 1.1(a) of this Agreement after the

Company and shall be in writing. Any denial by the Board of Directors of a claim for

Successor to Company. Any and all successors (whether direct or indirect, by
purchase, merger, consolidation or otherwise) to all or substantially all of the business
or assets of the Company shall be obligated to perform this Agreement to the same extent
that the Company would be required to perform it if no such succession had taken place. In
the event each and every successor of the Company fails to affirmatively assume in writing
the obligations of the Company under this Agreement at or prior to the effectiveness of
any succession, then such failure shall be a breach of this Agreement by the Company and
its successor. In the event of such a breach of this Agreement by the Company, the
Executive shall give written notice of such claimed breach to the Company and the Company
shall thereafter have ten (10) days within which to cure such breach by delivering to the
Executive a written assumption by the successor of the obligations of the Company under
this Agreement. In the event the successor does not cure such breach within such 10-day
period, then such breach by the Company and its successor shall constitute a termination
without Cause of the employment of the Executive in accordance with Section 4.1(a) of this
Agreement if the Executive elects to thereafter terminate his/her employment with the
Company or the successor of the Company within thirty (30) days immediately following the
expiration of such 10-day cure period of the Company/successor, except that for purposes
of implementing the foregoing, the date on which any such succession becomes effective
shall be deemed the Date of Termination of the Executive. As used in this Agreement,
Company shall mean the Company as defined above and any successor to its
business or assets as aforesaid, including but not limited to any person or entity which
assumes and agrees to perform this Agreement, by operation of law or otherwise.

6.2       
Successor to Executive. This Agreement shall inure to the benefit of and be
enforceable by the Executive and the Executives personal or legal representatives,
executors, administrators, successors, heirs, distributees, devisees and legatees. If the
Executive should die while any amount would still be payable to the Executive or his/her
family hereunder if the Executive had continued to live, all such amounts, unless
otherwise provided herein, shall be paid in accordance with the terms of this Agreement to
the executors, personal representatives or administrators of the Executives estate
for the benefit of the Executives heirs, distributees, devisees and legatees, as the
case may be in accordance with the Executives Will and estate.

6.3       Non-Compete.

(a)                 For
a period of six (6) months after the Date of Termination the Executive will           not
directly or indirectly:

(i)                 as
an individual proprietor, partner, stockholder, officer, employee, director,
          joint venturer, investor, lender, or in any other capacity whatsoever (other
          than as the holder of not more than one percent (1%) of the total outstanding
          stock of a publicly held company), engage in the business of developing,
          producing, marketing or selling products and/or services of the kind or type
          developed or being developed, produced, marketed or sold by the Company while
          the Executive was employed by the Company or its successors; or

8

---

(ii)                 recruit,
solicit or induce, or attempt to induce, any employee or employees of           the
Company to terminate their employment with, or otherwise cease their
          relationship with, the Company or its successors; or

(iii)                 solicit,
divert or take away, or attempt to divert or to take away, the business           or
patronage of any of the clients, customers or accounts, or prospective           clients,
customers or accounts, of the Company or its successors which were           contacted,
solicited or served by the Executive while employed by the Company or           its
successors.

(b)                 If
any restrictions set forth in this Section 6.3 are deemed to be unenforceable
          because it extends for too long a period of time or over too great a range of
          activities or in too broad a geographic area or for any other reason, then such
          restrictions shall be interpreted to extend only over the maximum period of
          time, maximum range of activities, maximum geographic area and/or whatever
other           provisions need to be changed so as to make it enforceable.

(c)                 The
restrictions contained in this Section 6.3 are necessary for the protection           of
the business and goodwill of the Company and its successors and are           considered
by the Executive to be reasonable for such purpose and part of the
          consideration for the parties to enter into this Agreement. The Executive
agrees           that any breach of this Section 6.3 will cause the Company substantial
and           irrevocable damage and therefore, in the event of any such breach, in
addition           to such other remedies which may be available, the Company and its
successors           shall have the right to seek specific performance and injunctive
relief.

8.1       
Employment by Subsidiary. For purposes of this Agreement, the Executives
employment with the Company shall not be deemed to have terminated solely as a result of
the Executive continuing to be employed by a wholly-owned subsidiary of the Company. In
the event the Executive is employed by a wholly-owned subsidiary of the Company, then the
parties agree that the provisions of this Agreement shall apply to Executives
employment with such subsidiary of the Company.

8.2       
Severability. The invalidity or unenforceability of any provision of this Agreement
shall not affect the continuing validity or enforceability of any other provision of this
Agreement, which shall remain in full force and effect. In the event any provision of this
Agreement is deemed to be invalid or unenforceable, then such invalid or unenforceable
provision shall be deemed to no longer be a part of this Agreement; provided, however that
the parties hereby authorize the arbitrators in any dispute to substitute a valid and
enforceable provision in lieu of such invalid or unenforceable provision, with such new
provision having as substantially similar result as possible to the invalid or
unenforceable provision.

8.3       
Injunctive Relief. The Company and the Executive agree that any breach of this
Agreement by either the Company or the Executive is likely to cause the non-breaching
party substantial and irrevocable damage and therefore, in the event of any such breach
and in addition to such other remedies which may be available, the non-breaching party
shall have the right to specific performance and injunctive relief.

8.4       
Governing Law. The validity, interpretation, construction and performance of this
Agreement shall be governed by the internal laws of the Commonwealth of Virginia, without
regard to conflicts of law principles. The parties hereto agree to personal jurisdiction
and venue in any court of competent jurisdiction located in or serving Herndon, Virginia.

8.5       
Waivers. No waiver by either party at any time of any breach of, or compliance
with, any provision of this Agreement to be performed by the other party shall be deemed a
waiver of that or any other provision at any subsequent time.

8.6       
Counterparts. This Agreement may be executed in counterparts, each of which shall
be deemed to be an original but both of which together shall constitute one and the same
instrument.
